Using US Spec ChAdeMo in Europe with a US Spec Model S

[miimura]

so i am asking again.. if I pulled 3 phase power into my T02 connection and had dual chargers, would I get 20 kW or 7kW?

It is not possible to put 3 phase power into a North American Tesla vehicle inlet. The pins simply are not there. If you had a 32A 3-Phase connection, the most you could get would be 32A L-N 230VAC, so it's ~7.4kW. Two phases would not be connected.

I rally don't understand why Tesla didn't make worldwide SuperChargers as one unique solution.


Frequency is not a problem, both US and EU Teslas are rated 45-65hz for their respective on-board AC chargers.
In the US, for historical reasons, Tesla uses it's own connector. In the EU the Mennekes standard is used. This
means the inlet on the US version of the car will not be able to use the European superchargers, at least, not
without a VERY special adapter being hand built.. Even then the VIN numbers for US models would have to be
authorized for use on the EU network. You will not be able
to use EU public charging without a specialist cable being built, or using a bit of adaption.. but that is not unusual,
many European chargers require the user to supply the cable specific to their car. The simplest way to achieve this i
s to use a standard EU Mennekes to J1772 cable, then use the US Tesla's included J1772 to “US Tesla connector”
adapter. The car will charge at public stations with this simple arrangement.
**All you have to buy is a 32 Amp Mennekes to J1772 cable for this to work properly.**

The next thing to be aware of it that in the EU the Mennekes standard allows the use of three phase AC charging
which is fairly common in some European areas. The US connector is single phase but at higher amperage.
Three phase power is only common in distribution, and industrial/commercial areas in the US. So your US Tesla
may charge slower from some stations that are three phase, because you will only be using one of the phases.

You may also use the US Tesla's UMC in Europe with hand built adapters. The US UMC includes a NEMA 5-15p
adapter (US domestic Mains) which charges at 12 amps maximum. The adapter UMC and on-board charger(s) will
accept any voltage between 85-265 VAC You may construct an adapter from NEMA 5-15r to CEE 7/4 (Type C/F, Schuko).
You may also want a NEMA 5-15r to BS1363 (British Mains). The US UMC also comes with a NEMA 14-50 adapter, other adapters
you may want would be NEMA 14-50r to any IEC 16 or 32 amp sockets. Those are the red & blue plugs Bjørn is using.
But with these kind of adapters you will always need to manually set the charge current to 32 or 16 amps because
the Tesla NEMA 14-50p adapter will by default will pass up to 40 amps. Also any adapters you use must be wired only for 230
volts because the US Charger will not Handle 400 volts AC.

I said it upthread and I will say it again... if Tesla wanted something proprietary in the US they could have just adopted the modified Mennekes Type 2 plug world wide. yes the T02 connector is somewhat smaller and easier to manage, but having the T02 connector forces Tesla to in effect support two charging standards when they only had to support one.

I get that the amount of people shipping cars from the USA to other parts of the world (and vice-versa) is rather small but when EM touts things like "being able to charge worldwide" at the M3 reveal, my stomach turns b/c Tesla has willingly/knowingly or not put up arbitrary barriers to this even as they proclaim otherwise.

I have shipped 3 cars from the USA to Europe in the past several years so it is something that is quite normal to me... even if it is not something most people will think about.

I assumed as much, but I wanted to get a confirmation. One of the things I am worried about when the time comes from me to wire a US Spec HPWC in Greece is that the electrician will balk at doing so b/c it is not "up to code" -- i suspect getting the electrical to wire a en EVSE with a euro J1772 plug will be easier -- or a Mennekes type 2.

in terms of future proofing my Mennekes type 2 outlet, I should install the 3-phase variety to begin with if I have 3-phase power in case whatever vehicle I replace my Model S with, most likely a Euro Spec MS a few years down the road, would be able to take advantage of that, correct? and my US Spec model S would charge fine, but ignore the extra 2 phases?

IMHO, the most future proof EVSE installation for Europe is a Type-2 socketed 32A 3-phase unit like the Keba Wallbox. You could use a simple Type-2 to Type-1 cable to charge your Model S with the provided North American J1772 to Tesla adapter. If you got a European Model S in the future, you would be able to charge it as fast as the car could take (22kW dual charger or 16.5kW facelift with 24A 3-ph upgrade).

I got this box for charging my US Tesla in Europe. I hope I will connect this soon.
I am aware that I will get only 7.4 kW charging but that is about 20 miles per hour? Right? If so that is not that bad.

 

[Galve2000]

looks good to me!!

I don't see a clear confirmation in this old thread that it is possible to use the US Chademo adapter with a US Tesla on Europe Chademo chargers, can anyone confirm if that should be possible ? The guy doing the tour with the Tesla Model 3 arrived in Europe and Chademo Charging did not work.

Model 3 does not (yet) support CHAdeMO...

Not at all ? (yet?).
Surprising. Just some software handshake that needs to be added to the firmware ?

Not yet... I have one in my under trunk that I usually carry with Our S... when it’s opened, then it can be used... until then Xuexue will have to go AC
